Octreotide, sold under the brand name Sandostatin among others, is an octapeptide that mimics natural somatostatin pharmacologically, though it is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone. It was first synthesized in 1979 and binds predominantly to the somatostatin receptors SSTR2 and SSTR5.

It was approved for use in the United States in 1988. Octreotide was approved for medical use in the European Union in 2022. As of June 2020, octreotide is the first oral somatostatin analog (SSA) approved by the FDA. It is on the World Health Organization's List of Essential Medicines.
